Allow users to move within the 3D space using the arrow keys or WASD.

Allow users to select fractals from multiple generations and add them to a list on the side. Also keep track of selected fractals for each generation instead of globally, and keep them when producing a new generation (with history tree, create a parallel node with the same fractals but different selection booleans)

Ran the program with the latest commit of C-Genetics and received the error:
Unable to parse character 'g' at position 30 in expression 'sin(1.8611627761312084/cos(x-g)_y)+0.7445142432870142_cos('1.1644862135176566*x)'

Certain fractals fail to produce any output in 3D render mode. Even altering the color equations produces nothing.

Here is a link to a problematic generation:

Load the generation with the 'L' key and try to render the middle fractal on the bottom row.

Maybe make them the same as variables, or set them manually before calculation. This will also help in generating values only for constants that are used, and therefore printing out only constants that are used.

This will allow the java gui program to outsource to render-mode and retrieve any tweaks that the user made while rendering.

Allow persistent generator that waits for input, generates the image (calc points on new thread and add to queue for drawing), and outputs to stdout when finished.

Provide a GUI so users can experiment with different equations for x,y,z/r,g,b.

Add support for specifying whether the thumbnails should be black and white or in color.

In render mode, the program should draw to screen periodically while the points are being calculated.
